Abstract: A conveyor drive roller with a replaceable sleeve defining a conveyor drive surface adapted to operatively engage a conveyor belt. The replaceable sleeve may be replaced with another replaceable sleeve defining another conveyor drive surface adapted to operatively engage another conveyor belt. A method of replacing the conveyor drive surface on the conveyor drive roller is also disclosed.

Abstract: A surface arrangement for a conveyor roller adapted for use in a conveyor system configured to support and move a conveyor medium, and a conveyor roller incorporating same. The surface arrangement has a cylindrical rotatable supporting surface, at least one shear stop member extending outwardly from the rotatable supporting surface, at least one lagging member positioned on the rotatable supporting surface, and a bond between the at least one lagging member and the rotatable supporting surface. The at least one lagging member is positioned on the rotatable supporting surface, with at least a portion of one end of the at least one lagging member abutting at least a portion of the side surface of the at least one shear stop member. The at least one shear stop member is adapted to resist movement of the at least one abutting lagging member in at least one direction along the circumference of the rotatable supporting surface to reduce a shear force exerted on the bond when the conveyor roller is in use.

Abstract: A conveyor drive roller for moving a conveyor medium. The conveyor roller has a hollow drum which is rotatably connected to a first and a second stationary shaft. An internal gear assembly is disposed inside the hollow drum and couples a motor to the hollow drum such that operation of the motor causes rotation of the hollow drum about the first and second stationary shafts. The hollow drum is configured to hold a liquid lubricant in contact with the internal gear assembly. Liquid lubricant flow paths are provided to move the liquid lubricant from inside the hollow drum to outside the hollow drum via the first or second stationary shafts, and vice versa. The liquid lubricant flow paths are configured for connection to a means for cooling the liquid lubricant.

Abstract: There is disclosed a conveyor drive roller of the type which may be used for example for supporting and driving a conveyor medium. The conveyor drive roller has a hollow drum which defines a cylindrically shaped rotatable supporting surface, and an internal surface. The hollow drum is rotatably connected to a first and a second support structure. An internal gear assembly is disposed inside of the hollow drum and operably connected to the internal surface of the hollow drum. The second support structure is adapted to permit a rotor of a motor located outside of the hollow drum to releasably couple to the internal gear assembly through the second support structure, so that when the rotor is coupled to the internal gear assembly, through the second support structure, rotation of the rotor is transmitted by the internal gear assembly to the hollow drum to cause rotation of the hollow drum about the first and second support structures.

Abstract: A key sprocket drive system for a conveyor belt having a drive drum having an outer surface. The outer surface of the drive drum is adapted to engage a securement means. A contoured collar has an inner surface and an outer surface. The contoured collar is adapted to receive the securement means and adapted to engage the outer surface of the drive drum at predetermined positions therefore providing defined gaps between the inner surface of the contoured collar and the outer surface of the drive drum. The key sprocket drive system further comprises a sprocket member having a generally annular configuration with externally facing teeth-like protrusions at spaced intervals. The sprocket member is adapted to receive the securement means whereby the securement means engage the sprocket member and the contoured collar to secure the sprocket member and the contoured collar to the drive drum. The teeth-like protrusions engage the conveyor belt so as to drive the conveyor belt.

Abstract: A self cleaning conveyor roller for supporting a conveyor media carrying contaminant materials. The conveyor roller consists of a drum defining a support surface, having a generally cylindrical shape, and being adapted to be supported for rotation, for supporting a conveyor media. The conveyor roller has a plurality of abutments on the support surface, raised above the support surface, and defining a series of spaced apart conveyor media support ridges lying on a circular configuration, concentric with the drum. The abutments are arranged in generally chevron shapes, around the drum. During rotation of the conveyor roller the abutments cause any debris or contaminants between the roller and the conveyor media to be guided out of the conveyor system. Also disclosed is a method of cleaning a conveyor roller.
